I created simple plugin with JBCefBrowser. I need to handle button or link click and get data from JavaScript in Java/Kotlin code on this JS event.

How to do it?

Thank you!

Ok. Created next solution

val javaScriptEngineProxy: JBCefJSQuery = JBCefJSQuery.create(browser as JBCefBrowserBase)

javaScriptEngineProxy.addHandler { result ->
    println(result)

    null
}

val injectedJavaScript = """
    window.goToLine = function() {                
        var filePath = document.getElementById("go-to-filepath").value
        var lineNumber = document.getElementById("go-to-line-number").value
        var goToPath = filePath + ":" + lineNumber
        ${javaScriptEngineProxy.inject("goToPath")}
    }
    
    """.trimIndent()

browser.cefBrowser.executeJavaScript(injectedJavaScript, browser.cefBrowser.url, 0)
